' Application filed August 12, 1926. Serial No. 128,836.

-This invention relates to blasting cartridges, explosives and. the like, and has articular application of means for 'at-tac mg a fuse to the cartridge in a manner to hold the fuse fixed relatively thereto in its given position, and to prevent the fuse from beingvseparated by being pulled out of the cartridge under any circumstance.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this application like numerals of reference indicate similar parts in the several views and wherein: I

Figure 1 is a fragmentary view in elevation showing the invention.

Figure 2 is a vertical sectional view therethrough.

Figure 3 is a plan view of the cap and bendable prongs.

Figure 4 is a view of the retaining sleeve for the fuse.

Referring to the drawing in detail 10 indicates the cartridge or explosive, while 11 represents the fuse.

In accordance with the present invention the fuse is received by a sleeve-like member 12 which is split longitudinally for a portion of its length from one end thereof, and the separated portions bent outwardly in a plane at a' right angle to the sleeve, which portions are indicated at 13 in Figure 4, and are used in conjunction with the cap to be presently described for holding the fuse fixed in its given position with relation to the cartridge. I

The capabove referred to includes a disklike portion or top 14 having a central opening 15 which registers with the sleeve 12 to receive the fuse 11 in the manner illustrated in Figure 2. Projecting from the periphery of :the disk are a plurality of bendable prongs 16 which are adapted to be bent downwardly along the sides of the cartridge 10 as shown in Figure 1, and having their pointed extremities 17 bend inwardly to bite into the body of the cartridge as illustrated in Figure 2. The cap 14 has a diameter equal to the diameter of the upper end of the cartridge upon which it reposes, and serves to prevent dampness from reaching that which rests upon the cap in a manner tov prevent the sleeve from slipping downwardly through the opening 15 of the latter.

The invention provides means whereby a fuse can be quickl and conveniently associated with a cartr dge of the class in question, holding the fuse in the center of the cartridge, and fixed relatively thereto, which is a much safer way than the ordinary present day manner of tying the fuse to the cartridge with a string or the like.

Vlhile it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, we desire to have it understood, that we do not limit ourselves to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What is claimed is:

1. Means for connecting a fuse with a cartridge, comprising a cap adapted to repose upon the upper end of the cartridge and provided with a central opening, a sleeve-like member adapted to receive the fuse and passed through said opening in the cap, and extensions formed on the lower end of the sleeve and arranged against the under side of the cap for holding the cap and sleeve associated.

2. Means for connecting a fuse with a Then l cartridge, comprising a cap adapted to repose on the upper end of the cartridge and provided with a central opening, bendable prongs depending from the cap and having offset extremities adapted to be embedded in the body of the cartridge, a sleeve-like member through which the fuse is passed,

said sleeve-like member extending through the opening in the cap and including laterally disposed extensions engaging the under side of the cap for holding the latter and said sleeve associated.

3. Means for attaching a fuse to a cartridge, comprising a cap adapted to repose upon the upper end of the cartridge and having a central 0 ening for the reception of said fuse, ben able prongs depending from the cap and having ofi'set extremities adapted to be embedded in said cartridge, 21, sleeve-lilfe member crimped about the fuse and promoting through the opening in said cap, extensions projecting laterally from the lower end of the sleeve and arranged against the under side of the cap, and a rib formed on said sleeve and bearing against the up- 1 per side of the cap for the purpose specified.

In testimony whereof we affix our signatures.
